September 15, 1976 Director of Nuclear Reactor Regulation US Nuclear Regulatory Commission Washington, DC 20555 DOCKET 50-155, LICENSE DPR BIG ROCK POINT PLANT By letter dated August 31, 1976, Consumers Power Company submitted radioactive effluent summaries for the Big Rock Point Plant for the period January 1, 1976 through June 30, 1976. Since that time, further review of these summaries has indicated an error in the June liquid effluent total. In addition, the infor-mation submitted did not include the Strontium 89/90 results for June because they were not available until recently. The attached table titled "Radioactive Liquid Releases" corrects the June error and also provides the strontium re-sults. Please substitute it for the corresponding table submitted with the August 31, 1976 letter.
